Pack for articles

ABSTRACT

A pack for two electric lamp bulbs includes a covering sleeve of oblong rectangular cross-section, and a containing sleeve of rectangular cross-section. An oblique partition extending across the rectangular containing sleeve between two opposite walls thereof divides its interior into two four-sided compartments open at both ends and receiving the bulbs. The bulbs are fitted into the compartments, via one end of the container sleeve, to lie side-by-side and head-to-tail. The partition, a gluing strip, and the containing sleeve are a folded single piece of material, the partition not having been cut from the containing sleeve. The latter is fittable into the covering sleeve, with the partition in position, by sliding in the containing sleeve with one of the aforesaid opposite walls leading, such that the other two walls lie face-to-face with the respective narrower covering sleeve walls.

SUMMARY OF THE INVENTION According to one aspect of the present invention, there is provided a pack for articles, comprising a covering sleeve open at both ends, a containing sleeve open at both ends of rectangular cross-section and fittable into said covering sleeve, and a partition wall for extending across the interior of said containing sleeve from one side of said containing sleeve towards an opposite side thereof to divide the interior of said rectangular containing sleeve into first and second four-sided compartments open at both ends for receiving first and second articles, respectively, said containing sleeve being fittable into said covering sleeve, with said partition wall in position dividing said interior as aforesaid, by sliding said containing sleeve into said covering sleeve in a direction from said one side to said opposite side.

According to another aspect of the present invention, there is provided a pack for an article, comprising a covering sleeve open at both ends and of substantially constant, oblong rectangular cross-section, and a sleeve member open at both ends and of substantially constant, rectangular cross-section and fittable into said covering sleeve by pushing thereinto in an axial direction of said covering sleeve perpendicularly to the axis of said containing sleeve such that two of the four walls of said containing sleeve lie face-to-face with the respective narrower walls of said covering sleeve.

According to a further aspect of the present invention, there is provided a pack for articles, comprising a covering sleeve open at both ends, a containing sleeve open at both ends and of rectangular cross-section and fittable into said covering sleeve by pushing thereinto in an axial direction of said covering sleeve perpendicularly to the axis of said containing sleeve, and a partition wall for extending across the interior of said containing sleeve to divide said interior into first and second compartments open at both ends of the containing sleeve for receiving first and second articles, respectively, said partition wall and the four walls of said containing sleeve being provided by a folded single piece of material, but none of said four walls having an aperture therein out of which said partition wall has been folded. I t

According to a yet further aspect of the present invention, there is provided a pack containing first and second elongate articles having heads thereof wider than tails thereof, the pack comprising a covering sleeve open at both ends, a containing sleeve open at both ends and of rectangular cross-section and fittable into said covering sleeve, and a partition wall extending one side to said opposite side has the advantage that the two articles may be retained in the containing sleeve by the covering sleeve almost immediately after the leading wall of the containing sleeve has entered the covering sleeve. Advantageously, the dimensions of the sleeves are such that the containing sleeve cannot be fitted into the covering sleeve except in said direction or the opposite direction. The arrangement whereby I two of the four walls of the containing sleeve lie faceto-face with the respective narrower walls of the covering sleeve saves material compared to a case where the two walls of the containing sleeve lie faceto-face with the respective wider walls of the covering sleeve. More over, the avoidance of cutting and folding the partition wall from any of the four walls of the containing sleeve permits a conventional die-cutting to be dispensed with and so simplifies and cheapens' production of the pack.

BRIEF DESCRIPTION OF THE DRAWING In order that the invention may be clearly understood and readily carried into, effect, reference will now be made, by way of example, to the sole FIGURE of the accompanying drawing, which is a perspective view of a pack for electric lamp bulbs.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawing, the pack is made of cardboard or the like, preferably corrugated board as shown, and consists of a covering sleeve 1 which is open at both ends and is of oblong rectangular crosssection. Corrugations 2 at the inside of the covering sleeve extend perpendicularly to the axis of the sleeve.

The sleeve is made of one piece of corrugated board in a manner known per se. The pack also includes a containing sleeve 3 which is of rectangular cross-section and is open at both ends. The sleeve 3 is fittable into the covering sleeve 1 and has been made from a single piece of corrugated board. This piece has been folded to form six walls 4 to 9, of which the walls 4 to 7 form the sides of the sleeve 3, the wall 8 forms a gluing strip glued to the wall 4, and the wall 9 forms a partition wall. The partition wall 9 extends obliquely across the interior of the containing sleeve 3 from the wall 4 to the opposite wall 6 to divide the interior of the sleeve 3 into two four-sided compartments l0 and 11 open at both ends of the sleeve 3.

From the upper end of the sleeve 3, the compart-' ments l0 and 11 receive as friction fits respective electric lamp bulbs 12 and 13, the wall 9 being formed with score lines 14 parallel to the axis of the sleeve 3, whereby the wall 9 can bend slightly to adapt itself to the contours of the bulbs 12 and 13. The bulbs 12 and 13 lie side-by-side in the sleeve 3 with the head (or glass end) of each bulb adjacent the tail (or socket end) of the other bulb. To fit the sleeve 3 into the sleeve 1 with the wall 9 and the bulbs 12 and 13 in position as shown, the sleeve 3 is pushed tothe left in the drawing and so slid into the sleeve 1. The corrugations 2 tend to retain the sleeve 3 in the sleeve 1.

The arrangement whereby the sleeve 3 is. slid into or out of the sleeve 1 in a direction of the wall 4-wall 6 axis has the advantage that both bulbs are retained in the sleeve 3 by the sleeve 1 almost immediately after the leading wall 4 or 6 has entered the sleeve 1, or until the trailing wall 4 or 6 has almost left the sleeve 1. This prevents any one of the bulbs 12 and 13 from falling through an open end of the sleeve 3 while the sleeve 3 is being pushed into or out of the sleeve 1. It will be appreciated that, if the sleeve 3 were slid into or out of the sleeve 1 in a direction of the wall 5wa1l 7 axis, one of the bulbs 12 and 13 would be free for some time to fall from an open end of the sleeve 3. For this reason, it is advantageous if the dimensions of the sleeves l and 3 are such that the sleeve 3 cannot be fitted into the sleeve 1 except in a direction of the wall 4wall 6 axis, i.e., cannot be inserted into the sleeve 1 on the wall 5-wall 7 axis and on the axis of the sleeve 3 itself.

Moreover, the fact that the two walls 5 and 7 of the containing sleeve 3 lie face-to-face withthe two narrower walls 15 and 16, respectively, of the sleeve 1 saves material compared to a case where two walls of the containing sleeve lie face-to-face with the two wider walls of the covering sleeve.

It will be appreciated that, since the partition wall 9 has not been cut and folded from any one of the walls 4 to 7, there is no corresponding aperture in one of the walls 4 to 7 and a conventional die-cutting is dispensed with. 1
